No, I don't know Fein. Interesting idea for exhaust though. The downside is
when you want to focus exhausted air through a hose you can't. I think the
main reason for noise with vacuums isn't air flow so much as the high RPM
motors.

Yeah, I went on the ShopVac site but couldn't find it. My local Home Depot
still stocks it though. It was around $130. The filters ain't cheap @$10
but I make them last by keeping them clean and blowing them out (kinda
defeats the whole HEPA deal though). One of the main features I like is the
chrome steel drum.

Honestly I don't think you need the second hose. This vacuum is pretty
powerful. If you get an intake close to the working end of the router it
will get all of the sawdust. That said ... I would go to a more conventional
dust collection system if you're running for hours at a time. I don't know
how well low end vacuums will hold up continuous duty.
